A system consists of a 100.0 g block of Al with a 1.75 g drop of liquid H2O on top of it. For
this problem, assume that any transfer of energy occurs only between these two materials.
Both the Al and the H2O are initially at 100.0 °C and then, due to an energy flow between the
aluminum and the water, the H2O converts to the gas phase without changing temperature.
